16 Claims.

This invention relates to railway rolling stock and consists in a novelsafety guard for brake bottom connections.

The main object of the invention is to provide a simple and efficientbottom connection safety guard which is associated with the means forsecuring a brake beam guard, guide or supporting strap to a truck part.

Another object is to provide means for yieldingly resisting rotation ofthe bottom rod guard and which tends to return the guard to its normalposition in case the guard is struck and tilted by an obstacle betweenthe rails.

These objects and others are attained by the structures illustrated inthe accompanying drawings, in which- Figure 1 is a perspective viewshowing portions of a railway truck and brake rigging.

Figure 2 is a detail view showing a modified bracket for securing theguard, guide or supporting strap to the spring plank.

Figure 3 is a view of a modification of the bottom rod guard.

Figure 4 is a detail vertical transverse section through the springplank and showing another modification of the guard.

Figure 5 is a vertical longitudinal section through the guard, guide orsupporting strap and illustrating another form of bottom rod guard.

Figure 6 is a detail view corresponding to Figure 5, but showing thebottom rod guard in tilted position.

Figure 7 illustrates another modification.

Figure 8 illustrates still another modification.

In Figure 1, a spring plank l of usual channel form has a bracket 2secured to the lower surface 7 thereof by means of rivets 3. Thebrackethas a recessed top web 4 and depending flanges 5 having holes 6receiving pins 7 which detachably secure the brake beam guard, guide orsupport strap 8 to the bracket. The brake rigging illustrated comprisesa truss-type brake beam including compression and tension members 9 and10 and a strut l1 pivoted to brake lever 12, the brake lever beingpinned at the bottom to a bottom connecting rod 13. Ears 14 onthe frontend of strut 11 mount a chair 14a which engages strap 8.

Each pin 7 includes a hooked portion 15 de pending from the bracket 2and extending beneath the adjacent bottom connection 13 and forming asafety guard for the bottom connection. 1

In Figure 2, the spring plank l'lhas depressions 18 in the horizontalweb which are perforated to receive the legs of one or more invertedU-shaped brackets 19. The brake beam guard, guide or supporting strap 16is secured between the legs of bracket 19 by pins 20, each having a.hole 21 at one end for a cotter key, and a hooked portion 22 at theother end extending beneath the bottom connection 23 and forming asafety guard therefor.

In Figure 3, pin 24 has one end extending between the flanges 25 of thebrake beam guard, 5 guide or support bracket 26, adepending sidewardlydisposed portion 2'7 extending beneath the bottom rod 28, and aflattened portion 29 at the other end secured to spring plank 30 by arivet or bolt 31. In this form the bottom rod safety guard is moresecurely fastened and is more rigid than those illustrated in Figures 1and 2, and, in case of loss of a brake lever pin, the bracket 26 isrelieved of much of the weight of the connecting rod. The end of the 75,loop 27 may be hooked over the upright flange of the spring plank, asindicated at 46 in Figure 4. This form of engagement of the safety guardwith the spring plank facilitates assembly and disassembly in case partsof the brake rigging or the guard, itself, are replaced. The loo-p 32may be further secured to the spring plank 33 by a bolt or rivet, ifdesired, the latter being indicated at 34.

In Figures 5 and 6, the resilient guard, guide or supporting strap 35 isslightly distorted in assembling with bracket 36 in order to preventrattling. Pin 37 has a flattened surface 38 (see Figure 6) between theflanges of bracket 36 for engaging strap 35. The yielding pressure ofthe strap 35 against this flattened surface increases the resistance ofthe pin to rotation. Moreover,

if the looped end portion 40 of the pin is struck by an obstacle in thetrack and tilted, as shown in Figure 6, the pin will tend to returnimmedi- 95. ately to its normal position.

' In Figure '7, a guard, guide or supporting strap 41 is detachablysecured to a wrought type of supporting bracket 42 by a straight pin43.. The pin at the head end mounts a bent 0. strap or loop 44 whichextends beneath the bottom connection 45 and is secured to spring plank39 by a rivet 50.

In Figure 8, the pin 47 has a closed loop 48 at one end which encirclesthe bottom connection 49. Thepin could be squared at the head end and aseparate loop provided, similar to the element. 44 in Figure 7.

In each of the figures, the brake beam guard, guide or support membersillustrated and their supporting brackets are of the types now generallyin use, and in each of the forms, except that shown in Figure '7, thelooped pin replaces the pin ordinarily used to detachably secure thebrake beam guard, guide or support member to the bracket. This bracketmight be secured to, or formed integral with, a truck member other thanthe spring plank, such as the bolster, a convenient transom, or an armon the side frame. The device has fewer parts than other devices atpresent used for accomplishing a similar purpose and is, accordingly,less expensive and more durable.

Obviously, various details of the structures illustrated might be variedwithin the spirit of the invention and the exclusive use of all suchvariations as come within the scope of the appended claims iscontemplated.

1. In combination, a railway truck part, flanges on said part, brakerigging including a bottom connection, a brake beam guard, guide orsupport member mounted between said flanges, and a pin-like elementextending between said flanges and securing said member to said part,said element having an end portion extending beneath said connection andsafeguarding the same.

2. A device for detachably securing a brake beam guard, guide or supportstrap to a truck part and including a movable pin having a dependinghooked portion for safeguarding a brake bottom connection.
